Abstract
Abstract A software package is described which resides in a color printing system and which automatically intercepts and colorizes monochrome documents (or re-colors color documents, if desired) that are sent to the color printer. The description includes pictorial flow charts and segments of code from an existing implementation in a Pascal-like language, implemented for documents expressed in a high-level page description language. The functionality of each major process in the software is explained in detail, including as examples the process of capturing and parsing user-specified modifications to the automatic coloring instructions, the process of coloring graphical objects according to their existing fill patterns, the process of coloring text and adding textual features such as dropshadows, and the process of coloring bitmaps. <IMAGE>

A method of generating a color print, comprising the steps of at a user's terminal, generating page description language commands describing each page of patterns, graphics, and text; allowing a user to add to the language, instructions which dictate in which color certain specified patterns, graphics, and text are to be printed; transmitting the language and instructions to a color printer, at the printer, changing the original page description language commands into new page description language which describe a page with a different set of patterns, graphics, text and colors deleting the instructions from the page description language cammands, and printing the desired color print by printing each item of patterns, graphics, and text as specified by the new page description language commands.
Claim 2
Independent Claim
116 words
The method of generating a color print comprising the steps of: at a user's terminal, generating page description language commands describing a page of patterns, graphics, and text; transmitting the language and instructions to a color printer; loading the printer with instructions which command in which colors certain specified patterns, graphics, and text are to be printed, changing the original page description language commands into new page description language commands which describe a page with a different set of patterns, graphics, text, and colors; deleting the instructions from the page description language commands, and printing the desired print by printing each item of patterns, graphics, and text as specified by the new page description language commands.
Claim 3
Independent Claim
133 words
A method of generating a color print comprising the steps of: loading a printer with first instructions which command in which colors certain specified patterns, graphics, and text are to be printed; at a user's terminal, generating page description language commands describing a page of pattern's, graphic, and text; allowing a user to add to the language, second instructions which command in which colors certain specified patterns, graphics, and text are to be printed, transmitting the language and instructions to a color printer, changing the original page description language commands into new page description language commands which describe a page with a different set of patterns, graphics, text, and colors, and printing the desired print by printing each item of patterns, graphics, and text as specified by the new page description language commands.
Claim 4
Dependent Claim
23 words
